Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary component for a chemical pipeline, in particular to a chemical pipeline safety cover. Background Art
[0002] Chemical pipelines are an indispensable and important part of chemical production. They are mainly used to transport various chemical products such as liquid, gaseous and solid, including petroleum, natural gas, chemical raw materials, intermediates, synthetics and finished products. Chemical pipelines are widely used. Since the length of chemical pipelines is fixed during production, chemical pipelines are generally sealed and connected by connectors between two adjacent chemical pipelines when in use. When the products transported inside the chemical pipeline (such as toxic gases) are corrosive, the sealing gaskets at the connection are easily corroded and damaged after long-term use, resulting in leakage at the connection between the two chemical pipelines (such as leakage of toxic gases), causing environmental pollution. Therefore, it is necessary to use a safety cover at the connection between the two chemical pipelines to strengthen protection.
[0003] The traditional safety cover at the connection between two chemical pipelines is mainly achieved by improving the performance of the sealing gasket, increasing the thickness of the sealing gasket or adding corrosion-resistant materials. It has the following defects: no matter how good the sealing effect is, it has a certain time limit. The traditional safety cover lacks the toxic gas detection function and cannot issue an alarm when harmful substances leak. There is a risk of causing safety accidents. The traditional safety cover is not equipped with an exhaust pipe and exhaust valve. When a leak occurs, the toxic gas cannot be discharged to a designated location through an external pipeline, which is easy to cause safety hazards and environmental pollution.

[0024] like Figure 1-Figure 5 As shown, the utility model also discloses a variety of more optimized specific structures:
[0025] In order to achieve a better alarm effect, the alarm includes a warning light 16 and a buzzer 15. The controller 14 is installed on the outer wall of the cover 12. The two buzzers 15 are respectively located on both sides of the controller 14. The two warning lights 16 are respectively located on the outsides of the two buzzers 15. The signal input ends of the two warning lights 16 and the signal input ends of the two buzzers 15 are respectively connected to the signal output ends of the controller 14.
[0026] In order to achieve a better audio alarm effect, each buzzer 15 is provided with a loudspeaker 6 connected to the cover 12 outside.
[0027] To facilitate processing and installation, the cover shell 12 includes a first half shell 121 and a second half shell 122 which are interconnected and have a semicircular cross-section. The outer diameter of the middle section of the first half shell 121 is greater than the outer diameters of the two ends, and the opening positions of the outer wall of the middle section are respectively provided with first connecting plates 3 extending toward the peripheral direction. The outer diameter of the middle section of the second half shell 122 is greater than the outer diameters of the two ends, and the opening positions of the outer wall of the middle section are respectively provided with second connecting plates 31 extending toward the peripheral direction. The first connecting plate 3 and the second connecting plate 31 are respectively provided with first connecting through holes 32, and a plurality of first connecting bolts 33 respectively pass through the corresponding first connecting through holes 32 and are locked by first connecting nuts 34. The gas sensor 13, the controller 14 and the alarm are installed on the first half shell 121.
[0028] In order to improve the sealing effect of the cover shell 12, a sealing gasket 123 is respectively provided on the inner side of the first half cover shell 121 and the inner side of the second half cover shell 122. The two ends of the two sealing gaskets 123 are respectively in close contact with the outer wall of the first pipe 1 and the outer wall of the second pipe 11, and the middle sections of the two sealing gaskets 123 are in close contact with each other.
[0029] In order to facilitate exhausting the toxic gas to a designated location through an external pipeline when a leak is detected, an exhaust pipe 4 is provided on the shell wall of the housing 12 , and an exhaust valve 41 is provided on the exhaust pipe 4 .
